Question 270719
Great progress so far:

c= Child admission
a= Adult admission 
c+a=450
$5c+$9a=$3,050
changed c+a=450 to c=450-a
substitution:
$5(450-a)+$9a=$3,050 
Not sure if my equations are right. Based off of how I solved a similiar problem. And I don't know how to simplify from there.
Could you please tell me if I'm on the right track and if so, how to solve from where I stopped?

So starting from where you left off:

5(450-a) + 9a = 3050

2250 - 5a + 9a = 3050
9a - 5a = 3050 - 2250
4a = 800
a = 200

c = 450 - a
c = 450 - 200
c = 250
